Hey guys,
My biggest problem on the PS section is the ratio/proportion questions. Does anyone have any tricks or tips? For example, when finding how an increase/decrease in one variable affects the equation. (I'm not talking in simple equations like F=ma). It takes me too long when questions ask about one variable, and that variable must be plugged into an additional equation to find out how some other variable in that equation is affected.
